My present invention relates to rinsing tubs or sinks of the type used in bar rooms, restaurants and at soda fountains, and in which the glass or cup is washed by dipping and sloshing in water maintained at desired level by a standpipe protruding upward from the drain and serving as a level gauge.

Rinsing tubs of the above type in commonpractice become deled, especially during rush hours, with refuse from the used glasses or cups, including not only unused lbeverage but also an accumulation 4oi! solid waste such as lemon and orange peels, cherry and olive pits, drinking straws, cigar and cigarette butts and match sticks. Such refuse in the rinsing water is not only unsanitary but disgusting to all but the most callous patrons, wholly aside from the fact that it is apt to impart a foreign taste to the beverage dispensed in the glass or cup supposedly cleansed in such tub.

An auxiliary sink for such refuse as can be poured out of the glass or cup occupies valuable space aside from its cost. y The dumping of the refuse of each glass or cup into a barbage can, prior to washing is objectionable not only for sanitary and aesthetic reasons but because during rush hours this would involve too much loss of time, aside from the fact that the solid refuse to be emptied could not readily be segregated from the unconsumed beverage to be discarded.

Among the objects of the invention are to provide an attachment of simple and rugged construction which may be applied in an instant to the conventional rinsing tub to convert the latter into a new entity by which the rinsing water is reliably protected from defllement with liquid or solid refuse. y Another object is to provide an attachment of the above type of simple and durable construction, devoid of valves or other mechanism and substantially proof against the possibility oi derangement.

Another object is to provide an attachment of the above type which may be readily and interchangeably used on any of the various types of rinsing tubs regardless of the size of drain provided therein.

Another object is to provide an attachment of the above type by which the liquid refuse is promptly drained without commingling with the rinsing water in the tubv and the solid refuse is segregated from such rinsing water, the overflow from which is continuously passed thereover so that the refuse is not exposed to access of bar room dies or vermin.

In the accompanying 'drawing in which are shown one or Imore of various possible embodiments of the several features of the invention,

Fig. 1 is a perspective view with parts in section of a rinsing tub incorporating the invention,

Fig. 2 is a view of the attachment in longitudinal cross-section and on a larger scale,

Fig. 3 is a transverse cross-sectional view taken on line 3--3 of Fig. 2, and i Fig. 4 is a dropped perspective view of the two elements making up the attachment, the outer or water level controller being in somewhat modiiied form, and.` the rubber plug being shown apart and prior to assembly thereto.v

Referring now to the drawing, the rinsing tub is the conventionalV box Ill, preferably lined as at II with tin, stainless steel or the like, and is disposed behind the bar of the tap room, the fountain `of a confectionery or drug store, or in the kitchen of a restaurant. Such rinsing tub has a drain hole vI2 through its bottom, lined with a metal bushing I3, to which the drain pipe I5 below said drain aperture is attached by means of a union I4 compressing a gasket I4' interposed between the bushing and the pipe. In ordinary constructions a standpipe (not shown) is afdxed in the drain collar and rises therefrom to the level at which the rinsing water is to be kept in the tub.

According to the present invention the conventional drain pipe is replaced by the unit shown installed in Fig. 1 and the structural details of` which are best shown in Fig. 2. This unit pref'- erably comprises a water level controller in the form of a specialized standpipe I6 which is fitted into the drain collar I3 at its lower end but is of considerably larger diameter thereabove, such pipe preferably flaring outwardly at its neck I'I from above the drain and being generally cupshaped, with its rim I8 of diameter two or three times that of the drain.

The specialized standpipe or cup described accommodate's therein, a removable refuse cup I9. This cup is preferably exteriorly convex to afford but a small space 20 with respect to the correspondinginner concavity of the standpipe I6. The cup I9 hasY a bottom` 2l perforated at 22 and an out-turned supporting rim bead 23 which in the embodiment shown, rests upon the corresponding rim bead I8 of the standpipe. The refuse cup is preferably of height such, that when supported in place as described, its perforated bottom is immediately above the neck I'l of the standpipe, as shown. If desired the refuse cup I9 could be supported by the rim of its bottom 2| in the stand pipe I8, or the support could be intermediate thel top and bottom of the refuse cup. Preferably the refuse cup is conformed for facility of removal thereof from the standpipe. desirably with an inturned peripheral-bead 24 slightly below its rim.

The standpipe I6 is preferably conformed for universal use in various rinsing tubs or sinks in use, some of which have smaller and others larger drain holes. For this purpose, the standpipe is preferably shown as a unitary stamping or molding and has a reduced outlet 2G preferably threaded or corrugated at 21, over which is removably mounted a rubber plug 28 of desired diameter, adapted to that of the drain opening, and which is plugged intocollar i2 for a watertight seal, as best shown in Fig. 2.

In use it is 'apparent that the level of the rinsing water W would be determined by the height of the standpipe I6 as shown in Fig. 1. The liquid and solid refuse in the cup or glass would in practice be dumped into the refuse cup I9, from which the liquid would pass through the perforated bottom 2l down the drain and the solid matter be intercepted in the cup. The rinsing water thus remains undeiiled by liquid or solid refuse and the scum washed from the surface of the used glass or cup oats on water W when the glass is sloshed therein. Due to the continuous supply of fresh water into the tub in accordance with the usual practice, such floating scum promptly flows over the rim 23 into the refuse cup I8, over the solid matter collected therein whence it passes to the drain. Accordingly, the solid refuse is kept out of contact with the air, it spreads no noxious odors and it is protected from access by ilies and other vermin. 'I'he rinsing water thus remains clean, and need not be frequently drained as in the case of conventional rinsing tubs, so that waste of time in periodically refilling the tub and waste of water are also obviated.

From time to time, after a substantial amount of solid refuse has accumulated in the refuse cup, the same can be readily removed by grasping its rim 23 with the thumb and the bead 24 with the fingers, for dumping its contents into a garbage can and it is then replaced in the standpipe.

In the modification shown in Fig. 4 the standpipe I6 is preferably somewhat taller than that of Fig. 1 and has overflow apertures 30 arranged peripherally thereabout, somewhat below its rim. These apertures of course determine the level of the rinsing water, which overows through said apertures and into the space between the standpipe and the refuse cup I9, the latter resting upon the rim I8 of the standpipe as in the embodiment of Fig. 2. While the alternative arrangement is practical, the embodiment of Fig. 2 is to be preferred because it maintains a continuous flow of water over the refuse in thecan I9.

It will thus be seen that there is herein described an inexpensive and thoroughly practical device for eliminating the objections to the conventional rinsing tub and segregating the refuse solid and liquid from the water in which the glass or cup is to be washed.

As many changes could be made in the above construction, and many apparently widely different embodiments of this invention could be made without departing from the scope of the claims, it is intended that all matter contained in the above description or snown in the accompanying drawing shall be interpretedas illustrative and not in a limiting sense.
